Method of planting a handle and a bottle parison to a mold of blow-molding modules for manufacturing plastic containers

Abstract

A method of planting a handle and a bottle parison to a mold of blow-molding modules, including the steps of: first, holding a handle temporarily on a handle positioning device; then, holding a bottle parison temporarily on a bottle parison positioning device while a bottle blowing mold is in a mold-breaking state; moving the handle downward into the bottle blowing mold through the handle positioning device; positioning the handle at a desired position while the bottle blowing mold is switched to the mold-closing state; and moving the bottle parison downward into the bottle blowing mold through the bottle parison positioning device, and clamping the bottle opening of the bottle parison at the same time.

What is claimed is: 
     
       1. A method of planting a handle and a bottle parison to a mold for blow-molding modules for manufacturing plastic containers, the blow-molding module including a rotary bracket, a bottle parison positioning device, a handle positioning device and a bottle blowing mold having a mold-breaking state and a mold-closing state, the method consisting of the steps of:
 holding the handle temporarily through the handle positioning device above the bottle blowing mold before the mold-breaking state; 
 holding the bottle parison temporarily through the bottle parison positioning device during the mold-breaking state; 
 moving the handle downward directly into a section of the bottle blowing mold corresponding with a bottle blowing chamber through the handle positioning device along a path parallel with the axis of the bottle parison; 
 holding the handle in a fixed manner in the bottle blowing chamber which is formed in the bottle blowing mold during the mold-closing state; and 
 moving the bottle parison downward into the bottle blowing mold through the bottle parison positioning device along a path parallel with the axis of the bottle parison and clamping tightly a bottle opening of the bottle parison. 
 
     
     
       2. The method of  claim 1 , wherein the bottle blowing mold is located on the rotary bracket, the bottle parison positioning device including a bottle parison holding portion, a bottle mouth clamping portion and a press cylinder, the bottle parison holding portion holding the bottle parison and being slidable up and down above the bottle blowing mold; the handle positioning device including an in-mold slide track and a handle holding portion to hold the handle and be slidable up and down above the bottle blowing mold. 
     
     
       3. The method of  claim 2 , wherein the bottle parison positioning device is located above the bottle blowing mold which holds the bottle parison temporarily by the press cylinder on the bottle parison holding portion in the mold-breaking state. 
     
     
       4. The method of  claim 3 , wherein the press cylinder moves the bottle parison downward along a path parallel with the axis of the bottle parison to be positioned on the bottle blowing mold in the mold-closing state, the bottle opening of the bottle parison being pressed by the bottle mouth clamping portion. 
     
     
       5. The method of  claim 2 , wherein the handle positioning device is located above the bottle blowing mold to hold temporarily the handle through the handle holding portion above the bottle blowing mold before the mold-breaking state. 
     
     
       6. The method of  claim 5 , wherein the held handle is moved downward through the in-mold track along a path parallel with the axis of the bottle parison and planted into the bottle blowing mold in the mold-breaking state. 
     
     
       7. The method of  claim 6 , wherein the handle planted in the bottle blowing mold is fixedly held in the bottle blowing mold through handle holding troughs to be positioned in the desired bottle blowing chamber in the mold-closing state.
